Table of Contents
I. Background Information II. Final Action III. Incorporation by Reference IV. Statutory and Executive Orders Review I. Background Information

On August 12, 2016, the EPA proposed to approve revisions to Ecology’s general air quality regulations contained in Chapter 173–400 Washington Administrative Code (WAC) and the State ambient air quality standards contained in Chapter 173–476 WAC (81 FR 53362). An explanation of the Clean Air Act requirements, a detailed analysis of the revisions, and the EPA’s reasons for proposing approval were provided in the notice of proposed rulemaking, and will not be restated here. The public comment period for this proposed rule ended on September 12, 2016. The EPA received no comments on the proposal.

II. Final Action

The EPA is approving, and incorporating by reference, the submitted revisions to Chapters 173– 400 and 173–476 WAC set forth below as amendments to 40 CFR part 52. We are also approving, but not incorporating by reference, the revised version of WAC 173–400–260 Conflict of Interest, state effective July 1, 2016. Consistent with prior actions on the Washington SIP, the EPA reviews and approves state and local clean air agency submissions to ensure they provide adequate enforcement authority and other general authority to implement and enforce the SIP. However, regulations describing such agency enforcement and other general authority are typically not incorporated by reference so as to avoid potential conflict with the EPA’s independent authorities. III. Incorporation by Reference

In this rule, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is finalizing the incorporation by reference as described in the amendments to 40 CFR part 52 set forth below. These materials have been approved by the EPA for inclusion in the State Implementation Plan, have been incorporated by reference by theEPA into that plan, are fully federallyenforceable under sections 110 and 113 of the CAA as of the effective date of the final rulemaking of EPA’s approval, and will be incorporated by reference by the Director of the Federal Register in the next update to the SIP compilation. 1 The EPA has made, and will continue to make, these materials generally available through www.regulations.gov and/or at the EPA Region 10 Office (please contact the person identified in the **FOR FURTHER INFORMATION CONTACT** section of this preamble for more information). IV. Statutory and Executive Orders Review

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA’s role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:

• Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);

• does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. );

• is certified as not having a significant economic impact on a


### 69386 Federal Register / Vol. 81, No. 194 / Thursday, October 6, 2016 / Rules and Regulations

substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq. );

• does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4);

• does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);

• is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

• is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

• is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and

• does not provide the EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

The SIP is not approved to apply on any Indian reservation land in Washington, except as specifically noted below, and is also not approved to apply in any other area where the EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). Washington’s SIP is approved to apply on non-trust land within the exterior boundaries of the Puyallup Indian Reservation, also known as the 1873 Survey Area. Under the Puyallup Tribe of Indians Settlement Act of 1989, 25 U.S.C. 1773, Congress explicitly provided state and local agencies in Washington authority over activities on non-trust lands within the 1873 Survey Area. Consistent with EPA policy, the EPA provided a consultation opportunity to the Puyallup Tribe in a letter dated July 13, 2016.

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. The EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register . A major rule cannot take effect until 60 days after it is published in the Federal Register . This action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).

Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 5, 2016. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2)).

**ACTION :**  Final rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is finalizing action on five permitting rules submitted as a revision to the Northern Sonoma County Air Pollution Control District (NSCAPCD or District) portion of the applicable state implementation plan (SIP) for the State of California pursuant to requirements under the Clean Air Act (CAA or Act). We are finalizing a limited approval and limited disapproval of two rules; we are finalizing approval of the remaining three permitting rules; and we are deleting three rules. The amended rules govern the issuance of permits for stationary sources, including review and permitting of minor sources, major sources and major modifications under part C of title I of the Act. The limited disapproval actions trigger an obligation for EPA to promulgate a Federal Implementation Plan (FIP) for the specific New Source Review (NSR) program deficiencies unless California submits and we approve SIP revisions that correct the deficiencies within two years of the final action.

**DATES :**  This rule will be effective on November 7, 2016.

**ADDRESSES :**  The EPA has established a docket for this action under Docket No. EPA–R09–OAR–2016–0240. All documents in the docket are listed on the http://www.regulations.gov Web site. Although listed in the index, some information is not publicly available,

We proposed a full approval of Rules 200, 230 and 240 because we determined that these rules improve the SIP and are consistent with the relevant CAA requirements. We proposed a limited approval of Rules 130 and 220 because we determined that these rules improve the SIP and are largely consistent with the relevant CAA requirements. We simultaneously proposed a limited disapproval of Rules 130 and 220 because some rule provisions conflict with section 110 and part C of the Act. These provisions include the following:

A. The definition of Significant in Rule 130 does not include lead as a pollutant or provide a significant emission rate. The rule also does not provide a public notice threshold for lead.

B. Rule 220 does not contain any provisions specifying that required air quality modeling shall be based on the applicable models, databases, and other requirements specified in Part 51 Appendix W; therefore, the requirements of 40 CFR 51.160(f) and 51.166(l) have not been meet.

C. The text in Rule 220, Subsection (b)(3) contains a significant typographical error (the word ‘‘not’’ is missing) concerning the requirements pertaining to stack height.
